Answer:
u<19
Step-by-step explanation:
70 > 3u+13
you subtract 13 to both sides
which will give you 57
then you divide 3 and 57
leaving you of with 19
so your answer will be u<19
Jessica bought 4 packages of birthday invitations for 16.95 per package including tax each package contained 12 birthday invitations one stamp coast 0.44 she plans to split the cost evenly with her mother how much money will Jessica mother need to give to Jessica
Answer:
Jessica's mum will give her 44.46
Step-by-step explanation:
To solve this, we will first of all need to get the total cost of sending the birthday invitations across. After that, we can now split the cost into two.
Cost of sending birthday invitations:
Package cost = 16.95
Number of packages bought = 4
total sum spent on packages = 4 X 16.95 = 67.8
Each package contains 12 invitations.
There are 4 packages.
Total number of invitations = 12 X 4 = 48 invitations
One stamp cost 0.44.
Putting stamps on all 48 invitations will cost 0.44 X 48 = 21.12
Therefore the total cost will be the total sum spent on packages +the total sum spent on stamps = 67.8 + 21.12 = 88.92
Her mum has agreed to pay half of this cost which is 88.92 / 2 = 44.46

The number is equal to 25.
Let the number be n.To write the word problem as an algebraic equation:
In this exercise, we are required to translate the word problem into a mathematical (algebraic) expression and solve for the unknown variable (number):
Translating the word problem into an algebraic expression, we have;
A number is doubled and then increased by 20:
[tex]2n + 20[/tex] ...equation 1.
The result is 5 less than 3 times the number:

-2.25x+8.75x+10-20 solve x pls
Answer:
im gonna assume the 10 - 20 is what the equation is = to if not x wouldnt be = to anything x = -1.5
Step-by-step explanation:
-2.25x + 8.75x = 10-20
-2.25x+ 8.75x = -10
6.50x = -10 divide both sides by 6.5
x = -1.5

Alina is 6 years older than Greg. Amy’s age is 2.5 times Alina's age. Amy is 40. How old is Greg?
A. 16
B.10
C. 15
D.10
Answer:
Hi friend! The answer is D. 10
I hope this helps!
Answer:
B) 10
Step-by-step explanation:
Assign variables to each person:
A=Alina's Age
M=Amy's Age
G=Greg's Age
Set up a system of equations given the information:
A=6+G
M=2.5A
M=40
Notice that M is already given, so we can plug that into the second equation:
40=2.5A
16=A
So Alina is 16 years old, but the problem asks for Greg's age, so we plug Alina's age in the first equation:
16=6+G
10=G
So Greg is 10 years old, therefore B is the correct answer.

Which graph represents f(x) = -2x^4
Answer:
Top right
Step-by-step explanation:
Because it is negative and that is the typical shape for x^4 functions
The graph represents the given function f(x) is attached below
Top right option graph is correct
Given :
The equation of a graph is given by
[tex]f(x)=-2x^4[/tex]
Lets look at the end behavior of the given function f(x)
The leading coefficient is negative that is -2
The highest exponent is 4 that is the degree is even
When the leading coefficient is negative and degree is even then the graph goes down on both sides
As x-> ∞, f(x)-> -∞
As x-> -∞, f(x)-> -∞
So , the graph on the top right is correct

Graph the line through the two points (-2,1) and (2,1). Based on the graph of the line only, determine the slope and y-intercept of the line.
part 2
write the equation, in slope-intercept form, of the line that passes through the points (-2,1) and (2,1)

Answer:
see below
Step-by-step explanation:
part 1
(-2,1) and (2,1)
Both points have the same y value
The slope is zero since it is a horizontal line and it crosses the y axis at y =1 so the y intercept is (0,1)
part 2
The equation of the line in slope intercept form is
y= mx+b where m is the slope and b is the y intercept

What is the image point of (4,5) after a translation left 5 units and down 3 units?
Answer:
(-1,2)
Step-by-step explanation:
Going left means the x value goes down. In this case, it went to the left 5 spaces. so, all you have to do is subtract 5 from 4 which is -1. When going down on a graph, the y value goes down as well. Subtract 3 from 5 and you get 2. Therefore, the answer is (-1, 2).
A basketball team played six games. In those games, the team won by 8 points, lost by 11, won by 7, won by 11, lost by 4, and won by 13. What was the mean difference in game scores over the six games?
Mean =sum of observations/ no.of observations
Mean=8+11+7+11+4+13/6
=54/6
mean=9
The mean difference in the game scores over six games is 2.5
What is mean difference?The mean difference measures the absolute difference between the mean value in two different groups.
Given is a basketball team which played six games such that in those games, the team won by 8 points, lost by 11, won by 7, won by 11, lost by 4, and won by 13 respectively.
The mean difference of the given data can be calculated using the following formula -
Mean Difference = (∑W / n) - (∑L / n)
Where -
(∑W / n) is the mean of games won.
and
(∑L / n) is the mean of games lost.
(∑W / n) = (8 + 7 + 11 + 13)/4 = 9.75
and
(∑L / n) = (11 + 4)/2 = 15/2 = 7.5
Mean difference = (∑W / n) - (∑L / n) = 9.75 - 7.5 = 2.5
Therefore, the mean difference in the game scores over six games is 2.5
